Jajce is a city in nortwestern Bosnia and Herzegovina. Because of its historical importance, its townscape value, its archeological remains and the beauty of its surroundings, the former royal town counts as one of the main destinations for travellers in Bosnia.

Jajce was first built in the 14th century and served as the capital of the independent Kingdom of Bosnia during its time. The town has gates as fortifications, as well as a castle with walls which lead to the various gates around the town. About 10–20 kilometres from Jajce lies the Komotin Castle and town area which is older but smaller than Jajce.
